Dam No. 4. The first dam was begun in 1832 and completed in 1834.
A new dam was constructed in 1856; the present dam was begun in
1906 and completed in 1909. The generating plant on the West
Virginia side uses horizontal shaft turbines connected by rope
drive to horizontal shaft generators, probably the last such
plant in the U.S.
